The report of the 19 th National Congress proposed that the construction of ecological civilization is a thousand-year plan for the sustainable development of the Chinese nation.In March 2022,Xi Jinping,General Secretary pointed out that the construction in Inner Mongolia become important ecological security barrier in north of China.Therefore,it is of great significance for the sustainable ecological development to study the difference and relationship of ecological footprint of Inner Mongolia and its 12 cities,reflect the dynamic relationship between different regions completely,and explore the influencing factors of ecological footprint.In this context,based on the actual land productivity of Inner Mongolia as the standard,this thesis firstly uses the improved three-dimensional model of ecological footprint to measure the balanced factor,yield factor and natural capital utilization in Inner Mongolia,and analyzes the change characteristics in Inner Mongolia and 12 cities from 2006 to 2020 from three aspects of time scale,land type composition and spatial distribution.And predict the variation trends of the next five years.Secondly,based on previous studies and the characteristic development status of animal husbandry in Inner Mongolia,nine indicators including urbanization rate,permanent population,per capita GDP,output value of secondary industry,output value of animal husbandry,total investment in fixed assets of the whole society,total retail value of consumer goods,expenditure of research and development funds and the number of patent applications from the population,economy,society and technology four aspects are selected to construct a panel data model to explore the influencing factors of ecological footprint.Furthermore,this thesis explores the relationship between economic growth and ecological environment based on the analysis results of economic factors as the main driving force.The Tapio decoupling model is used to analyze the decoupling of ecological pressure and economy in Inner Mongolia and 12 cities.At last,it puts forward the countermeasures for the sustainable development of Inner Mongolia ecological.The results draw the five conclusions.Firstly,the ecological footprint of Inner Mongolia is significantly larger than the ecological carrying capacity from 2006 to 2020,and it is gradually reduced over the next five years.Secondly,the ecological footprint of different land types is significantly different.The contribution of cultivated land is more than90%,which is higher than other land types.Then,the consumption levels of natural resources are different in the cities.The western and eastern regions consume more capital stock,while the central region occupies more capital flow.Next,Urbanization rate,per capita GDP,output value of secondary industry,output value of animal husbandry,and total retail sales of consumer goods have a positive impact on ecological footprint,while total investment in fixed assets has a negative impact on ecological footprint.The number of resident populations,research and development expenditure,and the number of patent applications have no significant impact on ecological footprint.Finally,the ecological pressure and economic development in Inner Mongolia are in a state of decoupling.Xilingol League,Bayannur City,Ordos City and other individual cities show expansionary negative decoupling from 2012 to 2016.Overall,the economic development and ecological resources utilization in Inner Mongolia are in a relatively coordinated state.According to the research results,countermeasures and suggestions are put forward for the ecological sustainable development of Inner Mongolia from the perspectives of adjusting energy utilization structure,increasing green technology innovation,accelerating industrial structure upgrading,carrying out multi-pollution coordinated treatment and coordinating the balanced development of the cities. |
